Class ConicGradient

java.lang.Object

com.codename1.ui.Gradient

com.codename1.ui.ConicGradient

All Implemented Interfaces:

Paint

public final class ConicGradient
extends Gradient

Conic (sweep) gradient. Mirrors CSS conic-gradient([from <angle>] [at <pos>], <stops>). fromAngleDegrees follows the CSS convention: 0 degrees points up (toward the top edge), sweep is clockwise.

Conic gradients have no notion of cycle method - the [0,1] stop range always wraps around the circle once.

Method Details

getKind

public byte getKind()

Description copied from class: Gradient

Returns one of KIND_LINEAR, KIND_RADIAL, KIND_CONIC.

Specified by:

getKind in class Gradient

getFromAngleDegrees

public float getFromAngleDegrees()

setFromAngleDegrees

public ConicGradient setFromAngleDegrees(float fromAngleDegrees)

getRelativeCenterX

public float getRelativeCenterX()

setRelativeCenterX

public ConicGradient setRelativeCenterX(float relativeCenterX)

getRelativeCenterY

public float getRelativeCenterY()

setRelativeCenterY

public ConicGradient setRelativeCenterY(float relativeCenterY)

sampleArgb

public int sampleArgb(int px,
 int py,
 int width,
 int height)

Description copied from class: Gradient

Software-rasterizer hook used by the default port implementation when no native gradient shader is available. Samples an ARGB color for the pixel at (px, py) within a rectangle of the given width / height. Ports overriding fillGradient directly do not call this.

Specified by:

sampleArgb in class Gradient

copy

public ConicGradient copy()

Description copied from class: Gradient

Returns a defensive deep copy. Implemented by each concrete subclass so async-paint queues can capture an immutable snapshot.

Specified by:
